Introduction

MARPOL Annex II & IBC Code Revision

Assignment of hazard profile to each substance

Vessels affected - oil products tankers,chemical carriers and other tankers carrying

noxious liquid substances Date of entering in force 1 January 2007

Impact of reclassification of certain substances

Handling of residues (stripping and discharge

requirements)

Procedures and Arrangements Manual

Substances Reclassification

Five-tier system changed to four-tier system

Each substance in IBC Chapters 17 and 18 hasbeen recategorized.

Evaluation includes aspects such as bio-accumulation, acute toxicity, chronic toxicity,biodegradation, long-term human health effectsand possible effect on marine wildlife/habitats.

Procedures to categorize substances not listed inChapters 17 or 18 and/or in MEPC 2/Circularswere defined.

Biofuels are currenty under consideration by IMO

Transportation of Ethanol (Ethyl Alcohol)

Listed in Charter 18 of IBC Code 2007 Editionas Category Z, therefore IBC Coderequirements do not apply.

Can be carried under a Noxious LiquidSubstance (NLS) Certificate.

NLS requirements of MARPOL Annex II

indicate lower limits of residue within the tanksand has revised limitations on the discharge ofsuch residues

Ethanol classification IBC Code


8/228

Ethanol Transportation Requirements

Oil Carrier requirements plus NLSrequirements of MARPOL Annex II forCategory Z:

Tank Stripping Requirements empty to themaximum extent for existing vessels, 75 liters

for vessel constructed or converted after 1January 2007

Underwater Discharge (not mandatory forvessels built before 1 January 2007)

Ethanol Transportation - ABS Requirements

Applicable Rules:

Steel Vessels requirements of Oil Carrier(Part 5C Chapters 1 or 2 of the Rules) +MARPOL Annex II (Category Z) +Administration

Steel Vesels under 90 m requirements of OilCarrier (Part 5) + Resolution A.673(16) +Administration

Steel Barges requirements of Oil Tank Barge(5-2-3 of the Steel Barges Rules) + MARPOLAnnex II (Category Z) + Administration


10/2210

Carriage of Ethanol - Operational Concerns

No Rule or mandatory requirements for specific

painting scheme Operators indicating that pure epoxy is not

recommended. Suitable coatings would beIsocyanate Epoxy, Novalac Expoxy and PhenolicEpoxy

Piping systems materials and componentsshould be suitable for Ethanol

Foam concentrate of the fixed deck foam systemshall be compatible with Ethanol

Tankers of 20K DWT and above require IGS.The acidity of Ethanol is affected duringtransportation by the presence of the CO2 fromthe inert gas generator


11/2211

Transportation of Vegetable Oils

Now classified under IBC Code and requires adouble hull tanker for carriage.

Certain vegetable oils can be carried in Type 2ships and others can be carried in Type 3.

Vegetable oil carried in deep tanks in existingdry cargo ships has been legislated separatelyin MEPC 48 (54) (tanks are to be no closerthan 760 mm from the shell plating).

Transportation of Vegetable Oils (cont.)

MARPOL Annex II permits an exemption of theAdministration for vegetable oils identified withfootnote k in Chapter 17 of IBC Code. Exemptionallows the carriage of such oils in NLS tankermeeting the requirements for ships Type 3 (insteadof 2), except for cargo tank location.

Wing tanks or spaces shall be arranged such thatcargo tanks are located inboard of the moulded line ofside shell plating nowhere less than 760 mm.

Double bottom tanks or spaces shall be arranged suchthat the distance between the bottom of cargo tanksand moulded line of bottom plating measured at right

angles to the bottom shell plating is not less than B/15(m) or 2.0 m at centerline, whichever is the lesser.Minimum distance shall be 1.0 m

The relevant certificate shall indicate exemptiongranted.

Every ship certified to carry substances of categoryX, Y or Z shall have on board a Manual approved bythe Administration

The main purpose of the Manual is to makeoperational procedures and physical arrangementsavailable to the ships officers

It is necessary to review the current Manual againstthe revised MARPOL Annex II to determine thosesections that will require amendment, in particularwith respect to the stripping requirements by thecorresponding Administration

To assist Owners in compiling the P&A Manual, a

template is available at ABS website
